Abstract: The invention relates to a pile joint, which comprises a first concrete pile, a second concrete pile, and a coupling system therebetween for connecting and locking the concrete piles relative to each other. The coupling system includes a lock housing and a lock spindle connectible to each other and provided with transverse holes in such a way that the lock housing's transverse holes and the lock spindle's transverse hole settle substantially in line with each other for receiving a locking pin when the lock housing and the lock spindle are connected to each other. In addition, the lock housing is provided with a locking ring for retaining the locking pin in a position locking the lock housing and the lock spindle to each other.
